ENCINO, LOS ANGELES — An arrest has been made in the deadly shooting of a longtime, award-winning “American Idol” music supervisor and her husband in their multi-million-dollar home in Los Angeles.

In a statement provided to our sister station KABC on Tuesday afternoon, a spokesperson for the singing competition TV series confirmed the deaths of Robin Kaye and her husband, Thomas Deluca.

Officers responded to a request for a welfare check at the home on White Oak Avenue around 2:30 p.m. Monday, according to the Los Angeles Police Department. That’s when they found the two victims with what appeared to be gunshot wounds to the head.

They were both pronounced dead at the scene. Law enforcement sources told ABC News that the victims were found shot to death in separate rooms inside the house.

The suspect was identified as 22-year-old Raymond Boodarian. Detectives believe he has no relationship to the victims. He was allegedly burglarizing the residence while the couple came home, and he shot and killed them during a struggle.

Sources tell ABC News that there is no evidence he is related to any burglary rings and was not working with anyone else. They believe it was an isolated event.

Detectives believe the murder happened on July 10 when LAPD got two calls for service for a possible burglary at the address. Surveillance video reportedly shows the suspect entering the home on the afternoon of July 10.

Officers reportedly responded to the calls for service that day, but could not get inside because the home is highly fortified. They saw no signs of burglary on the ground, and a helicopter that flew overhead saw no signs of burglary, so they left the scene.

According to the surveillance video, the suspect had been inside the home for about 30 minutes before the couple came home and confronted him.

Officials say the suspect did not force entry, and instead found an open way inside. After the call for a welfare check, officers made their way inside by shattering a back window.

In a statement provided to KABC on Tuesday afternoon, a spokesperson for the singing competition TV series confirmed the deaths of Robin Kaye and her husband, Thomas Deluca.

“We are devastated to hear of Robin and her dear husband, Tom’s, passing,” the statement from “American Idol” said. “Robin has been a cornerstone of the ‘Idol’ family since 2009 and was truly loved and respected by all who came in contact with her. Robin will remain in our hearts forever and we share our deepest sympathy with her family and friends during this difficult time.”

“We didn’t see or hear anything. My renter called 911 on Thursday because she saw somebody hopping the fence,” said neighbor Amee Faggen. “And I have no idea if that was related or not. They came and left, the helicopters and police came. And I heard from my other neighbor that yesterday, the police came to do a wellness check, and the family said they hadn’t heard from them in four days.”

Los Angeles County sheriff’s deputies showed up at the scene with a K9, and step ladder, and other tools. Video from the scene shows deputies atop a fence of the home, appearing to shake trees on the property.

Detectives have been scouring the neighborhood for video since the bodies were found, searching for clues pointing to what unfolded leading up to the victims’ deaths.

The investigation into the death of the couple is ongoing, with multiple agencies involved.
